Couldnt you have just used Camo, Gio, Ale & Trez? Which wouldnt work IMO.
You named basically a 4-1-3-1-1 formation. Currently we could, for example, use this...
Gigi
Cace-Canna-Chiellini-DC
Melo
Camo-Diego-Gio
Ale
Trez
We just have to hope we score 11 every game, cos that defensive unit looks like it'd leak 10 a game!
